当前信息存储呈现出容量和速率均较低的局面，将阵列激光器、波分复用技术以及多层镀膜有机统一的三维 信息存储方法应运而生。此方法主要通过光纤中耦合物镜对光斑自动拉近距离聚焦，读写海量信息，这将对三维存储寻道时 间的缩减起着重要作用。本文通过对存储系统原理和光盘系统标量衍射理论的分析、浅要探究计算机仿真结果。

Since the current information storage has low capacity and rate, 3d information storage method arises, with the unity of array laser, wavelength division multiplexing technology and multi-layer coating. This method mainly uses the optical fiber coupling lens to pull the focus of flare closer automatically, so that to read and write huge amounts of information. It will play an important role to reduce the three-dimensional storage seeking time. This article analyzes the principle of storage system and the theory of scalar diffraction of cd-rom system, and explores on the simulation results.
